Large-mining-height system capable of improving large-mining-height fully-mechanized mining efficiency

Abstract

The invention provides a large-mining-height system capable of improving the large-mining-height fully-mechanized mining efficiency, and belongs to the technical field of large mining heights. The system comprises a coal mining machine, a middle trough, a baffle ledge, a first guide assembly, double middle plates, a shovel plate ledge, a second guide assembly and a detection device, the coal mining machine can travel on the middle trough, the double middle plates comprise the upper middle plate and the lower middle plate, the upper middle plate and the lower middle plate are arranged between the baffle ledge and the shovel plate ledge, a hollow cavity is formed by the upper middle plate and the lower middle plate, the detection device is arranged in the hollow cavity, the first guide assembly is arranged at the upper part of the baffle ledge, the second guide assembly is arranged at the upper part of the shovel plate ledge, and the two guide assemblies are arranged on the middle troughto provide a running track for the coal mining machine, so that a toothed rail and a toothed rail seat on the middle trough are stressed uniformly, and the coal mining machine runs more stably; and the running state of the middle trough is detected through the detection device, so that the manual detection time is shortened, and the large-mining-height fully-mechanized mining efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of large mining heights, in particular to a large mining height system capable of improving the efficiency of fully mechanized mining with large mining heights. Background technique [0002] Large mining height and one-time full-thickness coal mining method is a long-arm coal mining method that uses mechanical one-time mining with a total thickness of 3.5-6 meters. It is limited by the stability of the preparation of the working face. It is used for coal seams with small dip angles and is limited by the height. , generally using fully mechanized mining technology; [0003] In the process of fully mechanized mining with large mining height, due to the long mining arm of the shearer and the large fully mechanized mining face, the compressive stress of the shearer on the middle groove is relatively large, which is easy to wear the middle groove, and during operation, the middle Other parts of the tank are easi...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention provides a large mining height system capable of improving the efficiency of fully mechanized mining at large mining heights, so as to solve the technical problem of manual detection of the middle tank, which consumes time and leads to low efficiency of fully mechanized mining at large mining heights
